How early should I get on before my reining class?

How early to get on before a reining class depends on the individual horse's warm-up needs, the logistics of the specific show, and what the rider knows about how their horse responds to the competition environment — and the correct answer varies enough between horses that a general time recommendation is less useful than understanding the principles that determine the appropriate timing. The goal is to arrive at the in-gate or the entrance to the show pen with the horse forward, soft, and settled — not fatigued from too long a warm-up and not cold and unready from too short one. For most horses competing at amateur levels, getting on forty-five minutes to an hour before the expected class time provides enough time for a complete walk-trot-lope warm-up, a few quality maneuver checks, and a period of standing and walking quietly before the class while not leaving so much time that the horse uses up its best mental and physical energy before the run begins. Horses that are fresh and take longer to settle in new environments may need to get on earlier; horses that warm up quickly and settle readily may need less time. The show schedule also matters — if the class ahead of yours is running quickly or slowly, monitor the schedule and adjust the warm-up start time accordingly rather than rigidly following a predetermined schedule. A trainer or experienced companion at the show can watch the class schedule and alert you to adjust the warm-up timing as the class unfolds, which is one of the practical reasons having support at early shows is valuable beyond just the riding guidance.
